Lenz, 26, said she and Lucas went to sleep in her bed at 9:30 p.m. Tuesday, but when she woke up Wednesday morning, he was no longer next to her. He wasn't in his room, and she raced outside and found him in the snow.

"I woke up into a nightmare," Lenz said. "This is nothing you want to wake up to. ... It's just not fair. ... He was my pride and joy."
